Comparison Between Community A And Community B

820 Words4 Pages

On October 6, 2016, our environmental science class explored biodiversity. We conducted a lab involving the biodiversity of cars in two parking lots that are at our school. We used the parking lots as "communities" and the make of each car in a specific parking lot a "species". We classified the parking lots into Community A and Community B. Community A represented the athletic parking lot and Community B represented the band parking lot, both lots hold students and factuality cars. Our class split in half, one group attained data for Community A while the other attained data for Community B. We acquired our data by counting and writing down the make of each car in the parking lot. After this each group tallied the same "species" together …show more content…

Then the groups used the data from each community to find the species richness, evenness, dominance, relative diversity, and the Shannon-Weiner Index for of that particular community. The diversity measurement table shows the reader the comparison between Community A and Community B. In Community A there were 49 different species and in Community B there were 40 different species. The groups configured this information by plugging in the data from each community into the equations, H= -sum(Pi In [Pi]) and E= H/In(R). (H) being the uncertainty of predicting a species, (Pi) being the relative abundance, (E) being the evenness, and (R) being the species richness. By the results of equation we could determine the evenness, relative diversity, and the Shannon-Weiner Index of each community. The species richness is how many species there are in a certain community, it does not mean how many individuals there are. The evenness of community is calculated with the equation E= H/In(R). The dominance of the community is based upon which species had a higher population than the rest. The relative diversity is based off of the Shannon-Weiner Index, if the answer is less than or equal to 3.2 it is a low diversity and if it is higher it is a high diversity. The Shannon-Weiner Index is calculated with the equation H= …show more content…

Community B has the fewer amount of species and number of individuals in its population between the two communities. The result of a lower population of species could be because of pollutants produced by humans. This could have harmed the environment in which the species lived, so much, not a large amount of species can adapt/live there. Also, the humans could have destroyed habitats and homes of the species that the species can no longer live there because they have no shelter. Humans can destroy habitats by deforestation, construction,

    Carefully describe what the p-value tells you about the difference between the means. - The average number of phytoplankton per mL of water is 13 phytoplankton/mL of water, and the average of zooplankton is 41 zooplankton/mL of water. The 2SE for phytoplankton is 11, for zooplankton it is 21. The p-value for this data is 0.0255; because this p-value is less than 0.05 one can conclude that the difference in averages (i.e. zooplankton being higher than average of phytoplankton) is statistically significantly different. In other words, the greater average number of zooplankton per mL is very unlikely to be due to chance variation and likely due to some outside

    Graph 1: H-Value averages The data in this graph is calculated by using the Shannon-Weaver formula to determine the diversity of species on A-mountain. H-values were averaged from the transect data recorded according to Table 1 and Table 2 on both sides of the mountains. The closer H is to 1, the higher the diversity in the area. The closer H is to 0, the lower the diversity in the area.

  • Red Colored Prey Hypothesis

    This meant that in the population there were already ten different color of prey that occurred naturally. However, when the environment was a blue background with colorful flowers and butterflies, many of the different colored prey had gone extinct and the red prey had the highest number of survivors. Also, environment two was pink, white, and black plaid and the prey that had the most number of survivors in that environment was white. This demonstrates that depending on the environment, different variations of a trait would be successful. It also demonstrates that the adaptations in this experiment depended on the environments.

    For this field excursion the coastal prairies and dune communities of the BML were explored. Community composition and interactions in these areas were areas of emphasis on the excursion, as well as morphological adaptations organisms use to survive in these landscapes. These coastal environments can be a harsh place for species to make a living. Factors such as solar radiation, desiccation, sand showering, coastal winds, nutrient deficient soil, invasive species, and structural instability are all factors species in these areas have to cope with. However, despite these challenges these communities have found a way to thrive and are teeming with life.

    However, the rate at which the species were discovered became less and less. This correlates with the Species Area Relationship (SAR) theory as proposed by Arrhenius. When graphed, in both plots we notice a curve. This to correlates within the SAR theory in a small area. As we did not analyze a large area, which encompassed multiple biomes, we did not find the “s” shape graph, which is evident in figure 1 in the literature review.

    Another problem is that animals lose their habitat. Mostly, animals need a minimal amount of space, where they can hunt, breed and expand their population. Only one bird can be comfortable with a branch of a tree, although large mammals (like Bengal tigers) need a lot more space. As human civilization expands, these natural habitats diminish - and their restricted

It works to support and empower all people in the area and it works alongside the community and families in the community. Most of the people that attend the program are adults that live with either their parent(s) or a family member (low income) in Bolton. To help reach out to and accommodate to families with lower income, the center charges a small fee for the adult to attend.

    A community, a complex term that often times elicits various feelings and definitions, generally implies that there are relationships between a group of people that share some common goals, values, the same geographical location, or, perhaps a way of life that reinforces one another. In a community, members choose to associate with, or connect to each other. However, it is only when we take a step back from the activities in our life’s, do we recognize reality and witness the social interactions that occur around us every day. The overarching purpose of this assignment was to go out into the community on two separate occasions to observe the social interactions- paying close attention to evidence of social networks, excluded or exclusive communities,

    To begin our experiment we created a food web. We created our food web by identifying what organisms were producers or consumer. If the animals were consumers, then we further grouped them into one of three categories: primary, secondary, or tertiary/apex. We did this to make it easier to later arrange them on the food web and find what it should eat. We started with producers.

  • Community Vs Neighborhood Analysis

    The community has had an unforgettable impact on the development of cultural values, and so should not be delegated to a small area. A community is a collection of individuals who share similar cultural values and traditions and act upon those values in such a way that the collective good of all is influenced. By contrast, a neighborhood is an area that can be defined on a city map. It is a collection of individuals that live in geographic proximity and often depend upon the same resources. Of course, this disparity in definitions leads to the question of how both communities and neighborhoods go through the process of formation.
